DataNumen for HDD Data Recovery: Review 2026

DataNumen scans formatted, corrupted, or repartitioned HDDs, with support for 430-plus file types. It can also search disk images. Those are respectable fundamentals for a small Windows utility.

The weak point is not the list of supported formats. It is the recovery workflow around them. Results can require considerable manual checking, while the app provides less useful context than Disk Drill about which files are likely to open correctly. DataNumen may be adequate for a recently deleted folder, though it is less convincing once a partition is RAW or badly damaged.

DataNumen can scan an image file, which is useful if you already created one elsewhere. The app does not offer the same clear, integrated byte-to-byte backup path that makes Disk Drill practical around a questionable HDD.

That matters because repeated full scans place extra load on a weak mechanical drive. There is also no comparable recovery-chance display or prominent disk-health workflow. For accidental deletion on a healthy disk, this may not matter. For bad sectors, clicking sounds, timeouts, or repeated disconnects, it matters a lot.

The result browser includes previews, filters, sorting, plus automatic renaming for duplicate names. It is enough to locate a handful of documents or photos after a simple deletion.

Large signature-based scans are less pleasant. Reconstructed HDD files may lose their original names or paths, which leaves the user opening many items one by one. Disk Drill offers a clearer preview experience, stronger filtering, plus recovery-chance indicators that help narrow the list before writing anything to the destination drive.

The basic process is uncomplicated: choose a disk, set scan options, review the result, then select an output folder. DataNumen also has modest hardware requirements, so it can run on older Windows PCs.

Still, the app looks like a utility from another era. Version 4.0 is listed as a 32-bit Windows application, despite running on x64 processors. Labels are understandable, though the software does little to explain why one scan mode is appropriate or where a recovered file should be saved. Disk Drill feels much easier during a stressful recovery job.

A single DataNumen Data Recovery license costs $49.95 during the listed promotion, reduced from $59.95. The license is delivered after purchase, while DataNumen advertises a 30-day guarantee.

The lower price is DataNumen's strongest argument. Still, saving roughly $39 compared with Disk Drill PRO's $89 option is not a great trade if previews, disk imaging, scan interpretation, or cross-platform access matter. Use the demo first. Never purchase merely because a filename appears in a result list.
